TAPALPA:The roar of machine guns and drone of helicopters shook the luxurious resort where Mexico’s most-wanted cartel boss hid on Sunday, plunging tourists enjoying the picturesque western Mexican town of Tapalpa into panic.

Nemesio Oseguera, the powerful Jalisco New Generation Cartel (CJNG) leader known as “El Mencho,” attempted to flee the audacious Mexican military operation in the mountainous area of the Jalisco state but was wounded during the escape and died while in transport to a hospital.

“It was terrifying... you could hear machine guns firing from the ground into the air and from the air to the ground,” a tourist who arrived at the resort the night before the operation told AFP, speaking on condition of anonymity for his safety.

The gunfire erupted around dawn.

“It gradually increased, and then the weapons were loud,” the man said, estimating the shootout lasted a couple of hours.
